I think, I am also stuck with this problem :/ I had a quick look at eglibc source code on kfreebsd-* and discover that this port use PTHREAD_SIGBASE  : /* Use signals #32, #33, #34 for internal linuxthreads communication */ #define PTHREAD_SIGBASE 32 [since RT is not handled by kfreebsd this seems obvious] In GDB, I've found that "lin_thread_get_thread_signals"  in charge of querying libc for restart and cancel signal : restart = get_signo ("__pthread_sig_restart"); cancel = get_signo ("__pthread_sig_cancel"); But I don't know : - if lin_thread_get_thread_signals is used in kfreebsd-* ? - does get_signo code work under kfreebsd ? Sorry for not being more helpful, hope someone skilled can jump into this.  ports/sysdeps/unix/bsd/bsd4.4/kfreebsd/kernel-features.h  gdb/linux-nat.c Cheers, -- Damien
